Properties

public override TableOptions SupportedTableOptions { get; }

Property Value

TableOptions

Methods

ConvertParameterType(Type, DbDataType)

public override Type ConvertParameterType(Type type, DbDataType dataType)

Parameters

type Type

dataType DbDataType

Returns

Type

CreateSqlBuilder(MappingSchema, DataOptions)

public override ISqlBuilder CreateSqlBuilder(MappingSchema mappingSchema, DataOptions dataOptions)

Parameters

mappingSchema MappingSchema

dataOptions DataOptions

Returns

ISqlBuilder

ExecuteScope(DataConnection)

Creates disposable object, which should be disposed by caller after database query execution completed. Could be used to execute provider's method with scope-specific settings, e.g. with Invariant culture to workaround incorrect culture handling in provider.

public override IExecutionScope ExecuteScope(DataConnection dataConnection)

Parameters

dataConnection DataConnection

Current data connection object.

Returns

IExecutionScope

Scoped execution disposable object or null if provider doesn't need scoped configuration.

GetQueryParameterNormalizer()

Returns instance of IQueryParametersNormalizer, which implements normalization logic for parameters of single query. E.g. it could include:

• trimming names that are too long
• removing/replacing unsupported characters
• name deduplication for parameters with same name

. For implementation without state it is recommended to return static instance. E.g. this could be done for providers with positional parameters that ignore names.

public override IQueryParametersNormalizer GetQueryParameterNormalizer()

Returns

IQueryParametersNormalizer

GetSchemaProvider()

public override ISchemaProvider GetSchemaProvider()

Returns

ISchemaProvider

GetSqlOptimizer(DataOptions)

public override ISqlOptimizer GetSqlOptimizer(DataOptions dataOptions)

Parameters

dataOptions DataOptions

Returns

ISqlOptimizer

InitCommand(DataConnection, DbCommand, CommandType, string, DataParameter[]?, bool)

Initializes DataConnection command object.

public override DbCommand InitCommand(DataConnection dataConnection, DbCommand command, CommandType commandType, string commandText, DataParameter[]? parameters, bool withParameters)

Parameters

dataConnection DataConnection

Data connection instance to initialize with new command.

command DbCommand

Command instance to initialize.

commandType CommandType

Type of command.

commandText string

Command SQL.

parameters DataParameter[]

Optional list of parameters to add to initialized command.

withParameters bool

Flag to indicate that command has parameters. Used to configure parameters support when method called without parameters and parameters added later to command.

Returns

DbCommand

Initialized command instance.

IsDBNullAllowed(DataOptions, DbDataReader, int)

public override bool? IsDBNullAllowed(DataOptions options, DbDataReader reader, int idx)

Parameters

options DataOptions

reader DbDataReader

idx int

Returns

bool?
